Ok, I'll check it for 3.0.8 short time after.
I remember too that you (and other user with SQLite-3.0 forum) cannot use any package moving to next phpBB version (i.e. moving to next 3.0.9) -- without changing it before run. I'll support these changes. Until my MOD will be add to registered phpBB version (planning add to 3.1.x)...

You didn't understand. If you have DB with SQLite 3.0 you use in previous version, then you use upgrade package to convert DB to next version. But without pre-run changing of upgrade package you cannot do the convert! Because upgrade package doesn't know about 'sqlite_3'!
Need change install/database_update.php before run update.

Oh yeah, sorry I forgot, that I made a reinstall, because of the different versions of sqlite. Sorry.

The thing is: Is SQLite3 faster for you than SQLite(2)? Because I'm not sure right now if it is really faster or slower than sqlite. The install took longer than with sqlite(2), but the database is smaller because of the better file format smaller.
